Rv: you didn't mention whether you are satisfied with your current carrier, except for the lack of miles, but if you are, I'd think very hard about switching. It costs money to change carriers, and if the problem is strictly insufficient miles, you may be jumping from the frying pan into the fire....There seems to be a consensus that van freight is not keeping up with the supply of available vans, whomever you drive for. Of course, if CTX assures you they can provide more miles, and you trust them, then do it - but I'm not getting that impression, from your question.
